, To all whom it may concern:

Be it known that I, Harm J. Dmm'rn, a citizen of the United States, at Kiowa, in the county of Barber and State of Kansas, have invented new and useful Improvements in Processes and Ap aratus for De-Aerating Water, of which t e following is a. specification.

This invention relates to a process and aplparatus for deaera and purifying water,

eing specially inten ed for use in connection with the manufacture of ice, and the invention consists briefly in subjecting the water to heat in a vacuum chamber, withdrawing the air and by means of a vacuum pump or the fie, and admi the water vapor to a condenser from whic the water of condensation is returned to the deaeratin chamber for use in the manufeature ice or for other urposes. V

In the accom wing forming 7 part of this speci dzation Figure 1 is a view oi the apparatus in side elevation, parts being broken away.

Fig. 2- is an end elevation.

The water to be deaerated and purified is introduced into the deaerating chamber or reservoir by means of inlet connection 12 and is there heated by the exhaust from a steam, oil or .gas engine, the inlet for the exhaust steam being shown at 15 and the outlet at 16. Chambers 17 and 18 at the.

heir ted in chamber 10' gases contained therein being expanded, pas to the condenser 20 through ipe 21. The water of condensation returns e m the condenser through the pipe to the decoreting chamber 10, and the air and gas are withdrawn through pipe 26 by means 0i a. vacuum pump or the like.

A spraying device 27 is provided above the cells of the condenser for the usual purpose. The deaerated and purified water is finally withdrawn from reservoir 10 through pipe 30, which may lead to atgump connecting with the ice molds, or wi any suitable receptacles One of the principal features of the invention is the treatment of the water, in the manner described in a chamber in which ,thedpressure is below atmospheric pressure. A rip pan is located below the condenser.

What is claimed is:-- c In an apparatus of the clam described, a

reservoir means for conducting a heat medium through a. body of water there i f,

a pluralit of condensing coils located adjacent to t e reservoir means for conducting expanded air, gas and vapor from the reservoir to the coils, a spraying device above said coils, an exhaust connection ior withdrawing air and gases and simultaneously reducing the pressure within the condensing coils below atmospheric pressure, means for returning condensation from the coils to the reservoir, and means for withdrawing the purified and deaerated water from the reservoir. p

In testimony whereof I afiix my signature.
